I hate it when she does this

I told my mom that I went to call our cousins coffee shop to order a thing of insta coffee cuz I’m almost out. Well I literally put 1 number in wrong and it went to voicemail so I left a voicemail. The number called me back and said it was from CA so I was confused and answer. They said I called the wrong number so I was like.. oops I’m sorry 😂😂she was super nice about it. So I tell my mom about it cuz I find it funny and she starts acting pissed off. I’m asking her why she’s pissed off and she says “you don’t pay your phone bill” and I’m like ?what does that have to do with it? It was California it’s not like it would’ve charged it. And she keeps arguing with me And I argue back of course cuz I’m like wtf is she mad about. And then she starts laughing. And she’s like “lighten up buttercup” ok but you were the one who was mad at me telling you something funny?
